MACHINE FOR CLEANING BRICK.

SPECIFICATION forming part of Letters Patent No. 388,939, dated September 4, 1888.

Application filed June 2, 1887. Serial No. 240,032. (No model.)

To all whom it may concern:

Be it known that I, J OHN H. WILLIAMs, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Cleaning Bricks, ofwhich the following is a specifi- Cation.

My invention has for its object to provide a machine for cleaning the adhering mortar or cement from bricks which have been once used in a wall or building and which it is desired to again employ in a like or similar way.

In cleaning the mortar from bricks by the mode now practiced the workman, separately handling each brick, with a hammer knocks the mortar off thcrefro m. This process is not only tedious, consuming a great deal of time in its performance, but unless great care is exercised the bricks are left with objectionably uneven surfaceathrough the clinging thereto of unremoved portions of the mortar or cement, and besides this many bricks are broken and so rendered worthless. By my invention these objections are overcome, the bricks being thereby expeditiously and thoroughly cleaned, the surfaces left even, and liability of breaking the bricks entirely avoided.

The invention will first be described in con nection with the drawings, and subsequently pointed out in the claims.

Of the drawings, Figure 1 represents a side elevation of my brick-cleaning machine. Fig. 2 represents a sectional front elevation of the same.

Similar letters indicate similar parts in both views.

In carrying out my invention I construct a frame, A, of suitable dimensions, form, and strength, in which isjournaled a rotary shaft, to, having one or more saws, toothed disks, or cutters, b, secured thereto. Said shaft and saws or cutters may be rotated by power or by hand in any suitable or known manner. The means herein shown, which are well adapted for a portable machine, consist of a belt or chain, a, running over a pulley or sprocketwheel, d, on the main shaft a, and a sprocketwheel or pulley, e, the journal-shaft f of which is suitably supported in the lower part of the frame. On the sh aft f is arranged a friction-clutch, g, of common construction,

contrived to drive sprocket-wheel cby treadle g, through the medium of strap or band h.

Spring t is devised for raising the treadlc toits normal position after having been depressed 5 by the foot of the operator, the springj in the strap or band It being for the purpose of allowing said strap to stretch or yield slightly, for reasons well understood in the operation of such contrivances.

B B represent arms or levers each pivoted or fulcrumed, as at 7;, to the rear of the frame, the forward or free end of said arms or levers being normally held up to or so as to project above the table Z by means of springs in opcr- 6 ating against the under side of the arms. The upper side of the forward end of each of said arms or levers is provided with a toothed or friction-faced bed, 12, for the reception of the brick to be cleaned.

O 0 indicate spring arms secured at their rear ends to arms 13 and projecting upwardly and forwardly, and having toothed or his tioned platens 0, similar to beds a, secured to the under surface of their forward ends, so that 7 when a brick is placed on the bed a the platen 0 may be brought down thereon to grasp and hold the same through the medium of handles p p, secured to the free ends of springarms 0.

parts are such that when a brick is placed in position between thej aws,consisting of the bed n and platen o, and barely grasped and held therebetween by the depression of spring-arm The construction and arrangement of tlfifs G through the medium of handlep, said brick 5 will be entirely above the saws or cutters b,- but by the depression of arm B against the tension of spring m,by further drawing down on handle p, the side or end of the brick so held may be gradually moved along in close proximity to the saw, the teeth of which will cut or knock the projecting particles of mortar or cement from the face of the brick, leaving it with an even and practically cleaned surface. of the brick, it may be moved-or reversed so as to clean the other side, edge, or end by presenting the same to the saw, as before.

If desired, two saws or cutters may be provided,so as to operate on both sides or ends of ice After cleaning one end, side, or edge so as to operate on each side of bed a in such manner as to be used alternately to first clean one side or end of the brick and then the other by merely shifting the position of the brick between the bed and platen. In the construction herein shown there are two arms, B, and their equipments, one adapted to receive and present the ends and sides or edges to the saws or cutters and the other adapted to grasp and hold the brick by its edges or sides, so that its faces or upper and lower sides may be presented to the saws, and this is the form in which I prefer to make the machine.

By the means and manner of operation eX- plained I am enabled to effect a speedy, and, to all intents and purposes, perfect cleaning of bricks, and attain the objects recited at the outset of this description.

It is obvious that changes may be made in the form and arrangement of parts or devices constituting my invention without departing from its nature or spirit.

Emery-wheels or other abrading or cutting disks may be used instead of saws.

It will be seen that the saws are located below the table Z, and that the bricks to be cleaned have to be depressed below said table through openings in the table before they can reach the saws, so that there is no danger of injury to the operator by contact with the saws. This is a point of considerable importance when it is considered that the operatives employed in the labor of cleaning bricks are usually ignorant and unintelligent.

Having thus described the invention, what I claim is- I j 1. A rotary saw or cutter, a movable bed for the reception of a brick to be cleaned, means, substantially as described, for clamping or holding the brick on the bed, and a handle whereby said bed may be moved or depressed jaws adapted to grasp a brick and move it up a and down through an aperture in said table, and a saw or rotary cutter mounted on an arbor below said table and guarded by the latter, as set forth.

4. A brick-cleaning machine consisting of a rotary saw or cutter, a movable holder to engage or hold a brick, and a handle connected with the holder, whereby the latter and the brick engaged thereby may be moved toward the saw or cutter, substantially as hereinbefore set forth.

In testimony whereof Ihavesigned my name to this specification,in the presence of two subscribing witnesses, this 26th day of May, A. D1887.
